After the concrete 16 is solidified, all the precast concrete formworks 11 are connected into a whole, so that the stability of the shell ring 10 is ensured.

The prefabricated concrete template 11 can be purchased from a building market directly, the size of the prefabricated concrete template 11 can be 3.1m multiplied by 12m, and different specifications are selected when the prefabricated concrete template is matched with different wind driven generators. The prefabricated wall panels 111 are flat-shaped, and the local position can be adjusted according to requirements, for example, a chamfer is arranged at the end, an inclined plane is arranged at the end, the lengths of two corresponding prefabricated wall panels 111, and the like. The lengths of the two corresponding prefabricated wall panels 111 may be the same or different, and may be set as required.

The main raw material (the prefabricated concrete template 11) of the tower can be directly purchased, so that a mould does not need to be prepared for independently opening the mould for the duct piece of the tower when the shell ring 10 is manufactured, and the investment cost is reduced; furthermore, the purchased precast concrete template 11 can be directly transported to a construction site for assembly, and the transportation cost is low.

In some embodiments, the tower further includes a plurality of prestressed steel strands disposed outside the shell segments 10, and both ends of the prestressed steel strands are respectively connected to different shell segments 10. The prestressed steel strands tension the shell sections 10 to improve the overall structural stability of the tower. The prestressed steel strands may also be arranged inside the shell ring 10 as required.

Referring to fig. 10, an epoxy resin mortar layer 20 connecting the two sections of the cylindrical sections 10 adjacent to each other is arranged between the two sections of the cylindrical sections 10 adjacent to each other; the thickness of the epoxy resin mortar layer 20 is in the range of 7mm to 13mm, and may be, for example, 8mm, 9mm, 10mm, 11mm, 12mm, or the like.

The epoxy resin mortar layer 20 has a strong bonding effect, and can improve the connection reliability between two sections of the shell ring 10 which are adjacent up and down. The thickness of the epoxy resin mortar layer 20 may be set according to the position of the shell ring 10 and the angle of the precast concrete form 11.

In some embodiments, the angle between the precast concrete form 11 and the horizontal plane is in the range of 87 ° to 90 °, for example: 88 °, 89 °, etc. That is, the prefabricated concrete form 11, which is at least a partial section of the tower, may be disposed in a non-vertical position, and referring to fig. 1a, the maximum transverse dimension of the bottom of the tower is greater than the maximum transverse dimension of the upper part.

Because some precast concrete templates 11 have certain inclination angle, and the top and the bottom of precast concrete template 11 are right angle, when the precast concrete template 11 that produces is placed aslant, the top has slight difference in height, in order to control this difference in height within 3mm, the inclination angle when the tower section is designed can be less than 3 degrees, the angle range of the precast concrete template 11 and the horizontal plane is 87 degrees-90 degrees. When the assembly field is poured, the top surface of the shell ring 10 can be poured into a plane. Leveling of the bottom of the shell ring 10 is completed by epoxy resin with the thickness of about 10mm, namely the upper shell ring 10 can be naturally flattened when being placed on the unhardened epoxy resin.
